Abstract: An inverter having a first busbar for connection to a positive pole of a battery and a second busbar for connection to a negative pole of the battery and a filter element that includes an annular core surrounding the first and the second busbar and made from a ferromagnetic material. It is proposed that a core made from a further ferromagnetic material to be provided in an intermediate space surrounded by the annular core and formed between the two busbars.

Abstract: The invention relates to an inverter having an intermediate circuit capacitor, the connections of which are connected to supply lines for current supply and to a switching device which includes a plurality of half-bridges, wherein the intermediate circuit capacitor has a prespecified intermediate circuit capacitance, the magnitude of which is such that a ripple voltage which is formed in the supply lines by switching processes in the switching device is reduced to a prespecified maximum ripple voltage under prespecified operating conditions. For the purpose of reducing differential-mode interference, the invention proposes that a plurality of intermediate circuit capacitors which are connected in parallel are provided, wherein a sum of the capacitances of the plurality of intermediate circuit capacitors corresponds to the intermediate circuit capacitance.

Abstract: The invention relates to an inverter having a first busbar for connection to a positive pole of a battery and a second busbar for connection to a negative pole of the battery and a filter element for reducing common-mode and differential-mode interference that includes an annular core surrounding the first and the second busbar and made from a ferromagnetic material. In order to reduce differential-mode interference, it is proposed according to the invention for a core made from a further ferromagnetic material to be provided in an intermediate space surrounded by the annular core and formed between the two busbars.

Abstract: An electric filter having means for buffering high-frequency interference in a high-current environment, comprising a feed-through conductor, a derivation conductor, and one or more capacitors. The one or more capacitors are switched between the feed-through conductor and the derivation conductor. The feed-through conductor is directed around the capacitor. A motor vehicle wiring system can be equipped with such a filter.
